Flexure

rosace_layout::flexure

Struct Flexure 

Source 
pub struct Flexure;
Expand description

ROSACE’s constraint-based layout engine.

Runs a three-pass layout:

  1. Measure — top-down constraint propagation (driven by this struct)
  2. Place — bottom-up size resolution (driven by this struct)
  3. Paint — handled by rosace-render

In Phase 1 the engine is invoked manually per-widget; automatic tree traversal is wired up in a later step.

Implementations§

Source§

impl Flexure

Source

pub fn layout_leaf(constraints: Constraints, natural_size: Size) -> LayoutResult

Run a layout pass for a leaf node that has no children.

The natural_size is clamped to constraints and returned inside a LayoutResult with an empty child_positions list.
